A rat mammary tumor model induced by the organophosphorous pesticides parathion and malathion, possibly through acetylcholinesterase inhibition.   The majority of new active substances (10 per year, on average) are tested in a two-year cancer bioassay study or a combined chronic/carcinogenicity rat study, often in combination with a second study in a second rodent species, even though the relevance of the latter has been questioned (Annys et al., , Billinton et al., , Van.

    Malathion (O,O-dimethyl-S-1,2-bis ethoxy carbonyl ethyl phosphorodithionate) is a non-systemic, wide-spectrum pesticide. It is widely used throughout the world for agricultural, residential, and public health purposes, mainly to enhance food production and to provide protection from disease vectors. Malathion preference over other organophosphate pesticides relates to its low . 64 synonyms of book from the Merriam-Webster Thesaurus, plus related words, definitions, and antonyms.
